Abstract

The invention provides a blood pressure measuring method and device, and belongs to the technical field of blood pressure measurement.The problems that existing blood pressure measuring equipment with no cuff cannot call computing parameters conveniently, and errors are likely to be caused are solved.The blood pressure measuring method comprises the steps that calibration data matched with user identity characteristic data is built and prestored through electrocardiogram wave signals at first; when a user measures blood pressure, the prestored calibration data of the user is extracted according to the g method comprises the steps that calibration data matched with user, and automatic identification of the user identity is achieved; the phenomenon that the user manually inputs identity information and selects calibration parameters is avoided, the trouble that identity information needs to be frequently and manually input to select calibration parameters on the condition that multiple users share equipment is solved, using convenience is improved, and error probability is reduced.The blood pressure measuring device is simple in hardware structure, convenient to use and operate and suitable for being used by multiple users at the same time.

Description

technical field [0001] The invention belongs to the technical field of blood pressure measurement, and in particular relates to a blood pressure measurement method and a blood pressure measurement device. Background technique [0002] Blood pressure measurement is the main method for the diagnosis, treatment and evaluation of the severity and classification of hypertension. Although the common inflatable electronic sphygmomanometer has mature technology, the measurement process is cumbersome and the user will feel uncomfortable when measuring. [0003] With the development of technology, there has been a cuffless blood pressure measurement device that does not require cuff inflation. This type of device is generally based on the principle of linear correlation between pulse wave transit time (PTT) and blood pressure. By detecting the human body's electrocardiogram ( ECG) and pulse wave (PPG) signal feature point time difference to calculate PTT, and calculate the blood press...
